Robert Cracknell Posted October 25 Share Posted October 25 Perhaps a basic question but is the centre of gravity in a helicopter in the same position as the main rotor shaft? Quote Link to comment Share on other sites More sharing options...
Allan Bennett Posted October 25 Share Posted October 25 Ideally that's where it should be. If it's forward or aft it's not so bad as it is with fixed-wing aircraft -- it simply means you'll always be applying either forward or rearward pitch control to keep it in a steady hover.

Futura57 Posted October 25 Share Posted October 25 For 3D flying I believe the CG on the main mast is preferable since it's likely to be flown in any direction. This is what I tend to do. I tip the heli on its side so the main shaft is horozontal, then hold the main blades vertically and let the fuselage pivot to see if it's tail heavy. However, I prefer a slightly forward CG for scale helis because they tend to sit better in the air. But that's me. Quote Link to comment Share on other sites More sharing options...
Paul De Tourtoulon Posted October 26 Share Posted October 26 Hold the helicopter on it's side using the main shaft, it should slowly go nose down. Quote Link to comment Share on other sites More sharing options...
